If you need or want Hershey font support I can push out a version with it pretty easily. No, I can't really use the Hershey fonts. I was just evaluating the T-Display to see if it suits my project. Your code was the quickest path to installing and testing. I understand what you did with the turtlep...

I ran into a case where I'm unable to clear fragments of prior text on a Writer line by appending blanks to the new text. This happens when the rightmost column has pixels. I tried but couldn't figure out how to use Label with my Writer class. I was able to clear the line by first writing blanks to ...

That's great work, I'm going to try out your driver as soon as my HX1230 gets here. You started out using 9-bit transfers with two bytes. But looking at the hardware SPI specs for the ESP32 here, http://docs.micropython.org/en/latest/library/machine.SPI.html , it says that number of bits is variable...

I couldn't resist rewriting this clock code using Peter Hinch's Writer class. I also used his font-to-py to generate the two fonts used in this script. The pictures show this script running on an ESP32 devkit. It imports the following files: pcd8544_fb.py ( https://github.com/mcauser/micropython-pcd...

It looks like the, "@micropython.native", did some good. It took 6.57 seconds to fill the screen with "Hello!"s previously, now it takes 4.11 seconds. That's a 37.5% reduction! There was one more module where I added the "@micropython.native" line. I also increased the SPI baud rate to the max that ...

(i.e. you can compile the C version into an .mpy file).

I think I found how to do that here, https://docs.micropython.org/en/latest/ ... atmod.html, but this effort's gonna have to wait.

The OP was using the Loboris port, which has all sorts of differences to upstream (including, as I discovered today, time.strftime) -- https://github.com/loboris/MicroPython_ESP32_psRAM_LoBo Thanks, I had no idea. Threading seems different too, so it might take a bit of effort to make this work wit...

Did this really work for you? Running this didn't seem to work. First the lack of indents had to be fixed, then uP complained about no strtfime. There's no strftime() method in the time module, is there?

How did you get this to run on an ESP32?

I have plenty RAM to burn so it doesn't matter that MPY files are bigger. I am hoping to get a performance improvement. I haven't tried @native. st7789py.py is devbis's code and has many functions. I don't understand it well enough to know which one is slow, so just wanted to speed up the whole modu...

I'm trying to speed up some code using the 'native' feature of the MicroPython cross compiler. So far, no luck. The ESP32 uses an xtensa processor, and "mpy_cross" has two architecture options that mention the xtensa, xtensa xtensawin I tried both with the following commands. Both times I got the "O...
